[PATCH v2 2/2] arm64: dts: qcom: monaco: Add iface clock and power domain for ice sdhc
From: Kuldeep Singh
Date: Thu Apr 09 2026 - 04:33:16 EST
Qualcomm in-line crypto engine (ICE) platform driver specifies and votes
for its own resources. Before accessing ICE hardware during probe, to
avoid potential unclocked register access issues (when clk_ignore_unused
is not passed on the kernel command line), in addition to the 'core'
clock the 'iface' clock should also be turned on by the driver. This can
only be done if power domain is enabled.
Specify both power domain and the iface clock.
